1. Introduction
The PPG Industries Fiber Glass Products, Inc. ("PPG") facility in Lexington, NC operates a wastewater
treatment plant ("WWTP") authorized by NPDES Permit No. NC0004626. The NPDES Permit was
modified with an effective date of March 1, 2013. This permit expires May 31, 2014. This document
includes the required application materials to renew the permit.
2. Permit Renewal Modifications Requested
Along with the required renewal application data and materials, PPG is also requesting that the new
permit include some changes based on current and future operations at the facility. PPG is requesting that
the monitoring for Cadmium and Thallium that were added in the 2012 permit modification be eliminated
based on all sampling data collected being non -detect. We are also requesting that the permit criteria for
Selenium be eliminated since all samples have been non -detect. In addition, based on long term data,
PPG is requesting reduced monitoring frequency for Total Residual Chlorine, TSS BOD and Fecal
ofiform. The facility is also requesting an increase in the permitted daily average flow from 600,000
gpd to 650,000 gpd based on increased projected flows from upcoming production changes.
a Cadmium, Thallium and Selenium Monitoring and Limits
N FNR issued a modified�ermit, effective March 1,2Qj3, tr,�int}
a new air pollution control wet scrubber. The permit includes quarterly mor
Thallium, and monthly monitoring for Selenium. The permit includes a Sel,
of 10.4 µg/1 and a Daily Maximum of 106.6 µg/l, which comes into effect 1V
This permit renewal includes a request for the removal of these
ion of a discharge from
.g for Cadmium and
monthly average limit
1, 2014.
and permit limits.
This request is justified based on effluent data demonstrating that these parameters were non -detectable in
all wastewater samples during the monitoring conducted March — September 2013. During the 2012
permit modification process, PPG noted that these parameters were not expected to be present in PPG
wastewater and were only detected due to contamination of samples by a pilot wet scrubber unit used to
finalize the design specifications for the wet scrubber device to be installed on PPGs equipment. PPG
requests that the monitoring requirements for Cadmium, Thallium and Selenium be removed from the
permit. PPG also requests that the limits on Selenium also be removed from the permit.
Data and justification for the permit monitoring request is attached in Appendix B.
b. Iterating of PPG Lexington Wastewater Treatment Plant
The PPG Industries Fiber Glass Products, Inc., Lexington, North Carolina facility has had a gradual
increase in the hydraulic influent to the wastewater treatment plant. This is related to changes in
production and other activities. The plant is currently rated at 0.6 MGD; however, PPG expects further
increased hydraulic load to the treatment plant as production operations are optimized.
Fiss Environmental Solutions Inc. (FISS) has reviewed the capacity of the PPG Lexington wastewater
treatment plant. This included a review of pumping and piping design, along with the capabilities of the
treatment plant to comply with NPDES criteria. Based on this evaluation and calculation review, it was

determined that the limiting factor, at the current design, is the sustaining capability to pump the effluent
discharge. Under current design, the limiting hydraulic capacity was determined to be 0.65 MGD. The
ability to comply with the NPDES criteria at this flow rate was evaluated by FISS, as shown in
Attachment C, and shows the plant can treat this hydraulic loading and comply with NPDES criteria.
Therefore, FISS recommends that the treatment plant capacity be increased to 0.65 MGD
Calculations confirming the capacity of the treatment plant to adequately treat the additional flow and
loading projected for the next permit term is attached in Appendix C.
C. Performance Based Reduction of Monitoring Frequency Request
U.S. EPA guidelines provide for a performance based reduction of NPDES permit monitoring
frequencies. In conjunction with our NPDES permit renewal Application Form 2C, PPG is requesting
reductions in monitoring frequency for Total Residual Chlorine (TRC), BOD- 5 day, Total Suspended
Solids (TSS), and Fecal Coliform. The PPG facility continues to maintain high standards for wastewater
treatment and takes pride in its excellent historical performance in regard to its NPDES permit
compliance. Based on the past two (2) year samples analyzed for these parameters having an average as
compared to the current permitted Monthly Average (or Daily Maximum for TRC), of less than 25%,
PPG is requested that the monitoring frequencies for these parameters be reduced to "once every two
months" for TRC and "once a quarter" for Fecal Coliform, BOD and TSS. Refer to the monitoring data
attached in Appendix A. This request is based on the U.S. EPA's Interim Guidance for Performance -
Based Reduction of NPDES Permit Monitoring Frequencies. As shown on Table 1 of the Performance -
Based Reduction of Monitoring Frequencies attached in Appendix D, for parameters where the ratio of
Long Term Effluent Average to Monthly Average Limit is < 25 %, the monitoring frequency can be
reduced as requested.

3. Sample Reporting and Averaging
Sample reporting and averaging was provided in Form 2C as per NC DENR DWQ's memo "Directions
for Completing Monthly Monitoring Reports" dated September 1, 2000. These instructions provide
guidelines with respect to rules for reporting and averaging less than detectable "<" values. (e.g., a
sample result with a value of less than the detectable limit is considered to equal "zero" when calculating
monthly and long-term arithmetic averages). Also per NC DENR DMR reporting guidelines, fecal
coliform monthly and long-term averages were calculated using a geometric mean, where values less than
the detection limit of #/100 ml were reported as #/100 ml.
The data reported on Form 2C is for the period September 1, 2011 through August 31, 2013 for all
parameters except for Cadmium, Selenium and Thallium. For these parameters, data reported on this form
includes additional data collected during September and October 2013.
4. Signature Authority
There is no change requested in signature authority for monthly monitoring report requirements.
Signature authority for monthly monitoring reports as a "Duly Authorized Representative" per 15A
NCAC 213.0506(b)(2)(1)), will remain unchanged and is delegated to the person holding the title of
Maintenance Manager.
5. Sludge Management Plan
PPG Industries generates both primary and secondary sludge residuals as part of the industrial
wastewater treatment process. The primary sludge results from a lime precipitation process and the
secondary sludge is generated in an activated sludge biological treatment plant.
A schematic of the sludge management system is presented in Figure No. 3. The waste primary and
secondary sludge is dewatered on a belt filter press.
The belt dewater press is a U.S. Filter model BPC-1600-7C. This is a 1.6 meter process with a solids
processing capacity of 9.6 dry tons/day (3,494 dry tons/yr). This unit dewaters the solids from the
stabilization decant/thickener. There is more than adequate capacity to handle all of the sludge
generated onsite. The dewatered solids drop into an open top roll off dumpster, and are disposed of at
the Davidson County Landfill. A copy of the landfill approval for this disposal is attached.
PPG typically operates this unit on a 4-5 day/week basis for 6 hours/day (24 - 30 hr/week operation).
This mode of operation can handle 100% of the solids generated. The system could be operated up to 7
days/week at 20 hr/day operation (140 hrs/week). Therefore, the system will use less than 20 percent
of the available dewatering capacity.
The PPG wastewater treatment system is designed to provide operating flexibility. Therefore, PPG can
adjust to changing waste loads and changes in environmental regulations.

RE: Approval Letter for Dewatered Sludge Waste
Dear Brigette,
We have contacted the NC Department of Environment and Natural Resources and have checked to make
sure that the Davidson County Landfill can accept the Dewatered Sludge generated from your Industry.
At this present time, the Davidson County Solid Waste Department will approve / and accept the new waste
stream (Dewatered Sludge) generated from PPG Industries. The tipping fee will be $10 per cubic yard
In the advent that local, state, or the Federal laws were to change in reference to disposal of this waste, this
agreement letter will be void.
Thank you,

Attached Description of Wastewater Treatment Process
PPG Industries Fiber Glass Products Inc. — Lexington, NC
The wastewater is generated from the fiberglass manufacturing operation, the boiler operations, non -
contact cooling blow down, plant sanitary wastewater and the sanitary wastewater from the American
Children's Home. A process flow schematic is attached (Figure 3). The wastewater treatment processes
includes screening of the process wastewater and comminutors for the sanitary wastewaters. All wastes
are then equalized, chemically treated using lime and ferric chloride and settled in a primary clarifier.
The primary clarifier effluent is treated in an activated sludge system followed by a chlorine contact
chamber, dechlorination and activated carbon columns. Currently 100% of the treated effluent is
discharged to North Potts Creek.
The primary and secondary sludges are combined in a stabilization decant/thickener followed by belt
press dewatering. The decanted supernatant can be returned to the wet well or treated separately in
one of the activated sludge aeration basins. The dewatered sludge is transported to the Davidson
County Landfill.
The data presented in Form 2C Section V is based on plant operating data for the period September
2012 to August 2013 as reported in the Monthly Discharge Monitoring Reports. Supplemental
effluent analysis was conducted on samples collected on October 17, 2013 and October 22, 2013 for

CONTINUED FROM PAGE 3 OF FORM 2-C 1 110000346082 001
PART C - If you are a primary industry and this outfall contains process wastewater, refer to Table 2o-2 in the instructions to determine which of the GC/MS fractions you must test for. Mark "X" in column 2-a for all such GC/MS
fractions that apply to your industry and for ALL toxic metals, cyanides, and total phenols. If you are not required to mark column 2-a (secondary industries, nonprocess wastewater outfalls, and nonrequired GCIMS
fractions), mark "X" in column 2-b for each pollutant you know or have reason to believe is present. Mark "X" in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant, you must
provide the results of at least one analysis for that pollutant. If you mark column 2b for any pollutant, you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be
discharged in concentrations of 10 ppb or greater. If you mark column 2b for acrolein, acrylonitrile, 2,4 dinitrophenol, or 2-methyl-4, 6 dinitrophenol, you must provide the results of at least one analysis for each of these
pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater. Otherwise, for pollutants for which you mark column 2b, you must either submit at least one analysis or
briefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part; please review each carefully. Complete one table (all 7 pages) for each outfall. See instructions for
additional details and requirements.

Appendix B
Permit Monitoring Revision Request
Request to Eliminate Thallium, Cadmium, Selenium Monitoring

1. Background
On October 10, 2012, PPG submitted analytical results to NCDENR for water samples collected during
operation of a pilot scrubber trial. A small pilot scale test scrubber was operated for 2 weeks on a slip -stream
of the furnace exhaust, and blowdown water was collected in totes and sampled. The samples were analyzed
in an attempt to profile potential constituents in water from a future full-scale scrubber that would be newly
constructed on site. The water samples were analyzed for metals, solids and organics.
The samples' results did not detect any materials expected from PPG's processes, however, some
unknown metals were detected. Small quantities of some metals detected in the pilot blowdown water
samples are believed to be contaminants from the rental pilot scrubber equipment, rather than process
exhaust. The pilot unit supplied by the vendor was used in trials in other manufacturing industries
before use at PPG. The most recent of which was a gold refining facility where they were looking to
achieve product recovery of precious metals; the owner of the scrubber noted it is possible for trace
amounts of metals to remain in the sump. The pilot scrubber's packed substrate may trap metal
contaminants and it is not possible to completely clean the substrate between uses. The vendor does
not replace packing between uses at different manufacturing sites. It is believed that the low -levels of
detected metals were artifacts from the pilot unit, and were not expected to be present in a newly
fabricated scrubber -and will not be expected in the effluent following full treatment by the wastewater
operations. Constituents in city water, fiber glass raw materials, and fuels were compared to the pilot
analytical results to assess which constituents may be present. Metals including thallium are not used as
raw materials, are not known to be present in any raw materials used at Lexington, and are not products
of natural gas combustion.
In summary, the data submitted to NCDENR on October 10, 2012 only reflected the pilot trial, and was
not representative of the blowdown from the proposed new scrubber or final effluent of the WWTP after
full treatment of the new scrubber's water.
2. 2012 Permit Modifications
Based on the absence of actual monitoring data, NCDENR issued the modified permit, effective March1, 2013
to include quarterly monitoring for Cadmium, and Thallium; and monthly monitoring for Selenium. The
permit includes a Selenium Monthly Average Limit of 10.4 µg/1 and a Daily Maximum of 106.6 µg/l.
NCDENR indicated that monitoring for Thallium was added to verify that it was not present in the discharge
from the new scrubber discharge. Cadmium and Selenium were added based on the results of a statistical
analysis of the effluent data which included the pilot scrubber discharge which was believed to be
unrepresentative of the full scale scrubber discharge.
3. Full Scale Data And Justification For Monitoring And Limit Removal

The full scale scrubber was installed in late February of 2013, and the facility has monitored for the new
parameters as part of the permit implementation. The current data shows that Thallium, Cadmium and
Selenium have not been detected in the WWTP effluent. Based on the analytical data with the scrubber in
operation, PPG requests that the monitoring requirements for Thallium and Cadmium be removed from the
facility's NPDES permit, and that the monitoring and limit be removed for Selenium. Table B-1 is a summary
of the analytical data collected to date on these three parameters.

such as highly toxic or bioaccumulative compounds.
3) Parameter -by -Parameter Performance History
At a minimum, the two most. recent years of monthly average effluent data
representative of current operating conditions for'the parameter at the particular
outfall will be used to calculate the -long term average discharge rate for use in Table
The baseline monitoring. frequencies in Table.I of this guidance will normally be
considered the level of monitoring in the existing effective NPDES permit. It is.
important to recognize that permittees that receive monitoring frequency reductions in
accordance with -Table I or Table 2 are still expected to* take all appropriate measures
to control both the average level of pollutants of concern in their discharge (mean) as
well as the variability of such parameters in the discharge (vatkncej, regardless of
any reductions in monitoring frequencies granted from the baseline levels. Reliance
on- monitoring the discharge at a reduced frequency as the sole means of tracking and
controlling.the discharge could increase the risk of violations.
